Title: Manufacture of field-effect transistor
Inventor: ARAI KAZUHIRO
IPC: H01L21/265
Filed: 1983-02-28
Abstract: PURPOSE:To manufacture an MESFET, drain dielectric resistance thereof is high and reliability thereon is excellent, with high yield and superior reproducibility at low cost by setting the titled transistor so that a peak in electron concentration is positioned near a crystal surface through an ion implantation at a preceding stage through an insulating film, removing the insulating film and executing the ion implantation at a subsequent stage and an annealing. CONSTITUTION:An insulating film such as an oxide film (SiO2) 46 is deposited first in order to form an ohmic contact layer (an N<+> layer) on an operating layer 41 shaped on a GaAs semi-insulating substrate 40 through an epitaxial growth method or an ion implantation method, and ions are implanted at a preceding stage. The SiO2 film 46 is etched by diluted fluoric acid and removed, and Si ions are implanted selectively to impurity layers 47 as an ion implantation at a subsequent stage at least once from the surface. Si Ions are activated through an annealing at a temperature of 850 deg.C, and N<+> layers 42 as the high concentration layers of source-drain regions are formed. The upper sections of the N<+> layers 42 are patterned as source-drain electrodes, and AuGe is evaporated.

Title: Power tool safety device
Inventor: ADACHI MICHIAKI
IPC: B25C7/00
Filed: 1997-02-17
Abstract: PROBLEM TO BE SOLVED: To prevent the trigger of a power tool from being operated erroneously. SOLUTION: This power tool safety device is provided with a lock lever 13 fitted between a trigger lever 12 and a grip 10, a lock pin 14 fitted at the back of the trigger lever 12, and a hook part 13a on the opposite surface of the trigger lever 12 of the lock lever 13. When the lock lever 13 is pulled, the lock lever retreats to the outside of the lock pin 14 of the trigger lever, so that a starting can be operated. When the trigger lever 12 is pulled without operating the lock lever 13, the lock pin 14 comes into contact with the lock lever for trigger-locking. When the lock lever 13 is pulled from the trigger locking condition, the hook part 13a of the lock lever comes into contact with the lock pin 14, the lock lever is inhibited from rotating, so that the trigger locking is not released. Even if the lock lever 13 is pulled erroneously while a nailing machine is being moved with the trigger lever 12 pulled, the trigger lever is prevented form rotating until it reaches its starting position.

Abstract: PROBLEM TO BE SOLVED: To prevent an occurrence of a jam by preventing the transfer paper from stopping while the paper is caught by a nipped part between a feed roller and a reverse roller of a paper sheet feeding device. SOLUTION: In this device the rotation of a feed clutch and a reverse clutch is turned on according to a paper feed starting signal, so that a transfer paper 2 is called by a pick-up roller 3 in order to be drawn out from a paper sheet feeding tray 1. As soon as the tail end of the transfer paper 2 passes the nipping part between a feed roller 4 and a reverse roller 5, the rotation of the feed roller 4 and the reverse roller 5 is reversed by the drive of a reverse shaft 8, so that the transfer paper 2, whose tail end still remains in the nipping part between the feed roller 4 and the reverse roller 5, is returned to the paper feeding tray (1) side. After this, when a paper feeding sensor indicates OFF, the reverse clutch is turned OFF.

Title: Electromagnetically lockup type actuator
Inventor: KAMIMURA TAMIO
IPC: B60T8/36
Filed: 1978-03-24
Abstract: PURPOSE: To smoothly and alternately vary the pressure of fluid in a fluid passage, by alternately applying reverse electrical currents to a solenoid to repeat the reciprocation of a plunger.  
     CONSTITUTION: When a reverse electrical current for producing a magnetomotive force almost equal to that of a permanent magnet 4 is applied to the solenoid 5 as passages 8, 9 remain connected to each other, there is no magnetic flux in a magnetic circuit and a disc-shaped armature is released from the magnetic force. Thus, the plunger 1 is moved rightward by the fluid pressure in the passage 8. At that time, a check valve 10 closes most of an opening 14 first. However, a bleeder valve 11 is open to permit a small quantity of fluid to pass through a restricting passage provided between the valves 10, 11. When the plunger 1 is moved further, the opening 14 is totally closed by the valve 11. Since the opening 14 is sequentially closed by the valves 10, 11, the sharp rise in the fluid pressure in the passage 8 is prevented.

Title: Gear shift control device of automatic transmission
Inventor: MUNETOU KOUJI
IPC: B60W10/06
Filed: 1989-02-15
Abstract: PURPOSE:To enhance the durability of a friction element by changing a transmission line in the direction in which the calorific value of the generated friction heat drops, when the fluid temp. of a power system is over a certain value and either of the engine load and revolving speed exceeds the specified value. CONSTITUTION:In a shift control device of an automatic transmission, a temp. sensing means senses fluid temp. flowing in a power system, a revolving speed sensing means does the revolving speed of the power system, and a load sensing means the engine load. When the sensed fluid temp. is over a certain value, and if a judging means judges that at least either of the sensed engine load and revolving speed of power system has exceeded the specified value, so a transmission line altering means alters the transmission means in the direction in which the calorific value of the generated friction heat is going to sink. Thus rise of the fluid temp. in an automatic transmission is suppressed within a range not impairing the running feeling, and thus durability of the friction element can be enhanced.

Filed: 1985-02-22
Abstract: PURPOSE:To make a direct current loop circuit small in size and light in weight by inserting an opening and closing element between a base terminal, the first and third resistances, and a condenser, in a circuit used in a direct current trunk or the like. CONSTITUTION:In an electronic inductor circuit, a photoisolator 10 and a resis tance 11 as an opening and closing element are inserted in series between a base terminal of a transistor 5, resistances 6 and 8, and a condenser 9. When the photoisolator 10 is set to an interrupted state, the transistor 5 is set to an interrupted state and the direct current is disconnected. A time constant of a discharging is completely long. During repeating a dial pulse or the like when the photoisolator 10 in an interrupted state is conductive again in a short time, the condenser 9 is hardly discharged but charged, and a transition phenome non when the conductive state of the photoisolator 10 is changed is considerably decreased.

Title: Converting circuit for direct current
Inventor: HATA YOSHISADA
IPC: H02M7/537
Filed: 1982-03-05
Abstract: PURPOSE:To obtain stable switching operation by reducing the control currents of a switching element in response to load when the state of load is lightened. CONSTITUTION:Pulse voltage signals generated from a pulse generating circuit 1 are pulse-width modulated by a pulse width modulation circuit 2 in response to input/output voltage, and a predetermined-width pulse waveform is obtained. The output signals are applied to the base of the transistor of a voltage regulating circuit 10. When the state of load is lightened, the peak currents of the turn-ON base currents IB1 of a switching transistor Q3 can be reduced because output voltage Eo reduces in response to the change. Accordingly, the collector currents of the switching transistor Q3 are interrupted steeply, thus enabling stable control.
